A shaft 16 is journaled 5 flow of the exhaust gases from the internal comthrough said casing 14 and housing 15, as shown 5 bustion engine will operate an electrical generaat 1'7, and upon this shaft, within the casing 14, tor from which a current is led through a resistis mounted a turbine wheel 18, the blades 19 of ance unit suitably located in the dash in the front which are adapted to rotate through the opening of the car. 7 13 of the pipe '7, the ends of the blades being Another object is to provide in combination curved as shown to conform to the cross sectional 10 with the exhaust pipe of an automobile having curvature of the pipe and being adapted to move an internal combustion engine, a turbine wheel closely to but not to contact with the outer wall of operatively mounted through an opening in such the pipe '7. A conventional electric generator exhaust pipe so as to be driven by the flow of 20 (not shown in detail) is mounted within the 15 gases through the pipe, a generator connected housing 15, one element thereof, as the armature 5 to the turbine wheel, an electrical heating unit (not shown) being mounted upon the portion of suitably located upon the automobile, and com the shaft 16 extended within said housing, and ductors for leading current from the generator to the other element, as the field, (not shown) being. the said heating unit. supported from the inner walls of the housing.

A to the accompanying drawing as setting forth gate valve 23 is mounted upon a pivot pin 24 loa practical embodiment of the invention, and cated interiorly at the juncture of the pipes '7 and 25 wherein a 8, at the engine end of the assembly, an end 28 25 Figure l is an elevation partly in section, of the of the pin being extended exteriorly. The valve forward or engine end, showing the engine block 23 is controlled by the levers 25, 26, 27 pivotally and seat in full lines and the instrument board, connected together, the lever 25 being rigidly dash or foot board and a portion of the bottom joined to the extended end 28 of the pivot pin being shown mounted in connection therewith. 29 through the instrument board 5, and is pro- Figure 2 is a longitudinal section upon a greatly vided with a pivot bearing 30.

I claim:

An energizing means for electric heaters as applied to automobiles having an internal combustion engine, the same comprising in combination with the exhaust pipe of the engine the said exhaust pipe having a section cut away, a double pipe section placed in lieu of the cut away exhaust pipe section, the pipes at the doublepipesection including Y-coupiings or connection 'witln the ends of the exhaust pipe and intermediate arcuate pipe sections extended between the branches of the Y-couplings thereby providing an intermediate casing space between the two arcuate pipe sections, one of the double pipes having an opening in its inner side facing the other double pipe, a casing mounted over the said opening and disposed within the said space provided between the double pipes, a turbine wheel journaled in the casing and playing thru the said opening of the one pipe, an electric generator connected to the turbine wheel, and a gate valve pivotally mounted atthe iunction of the branches of the Y-coupling nearest the engine and adapted to close alternately the said arcuate pipe sections.
